Dear All, I have a question would like to ask regarding on the ssid i create by using "open" security with splash page settings, and the splash behavior have set to every 2 hours, and our customers reported that after they connected to this ssid, and they need to manual reconnect the ssid in with landing pages popup again in order to re-connect after they close the screen on their phone, but the connected time is still not yet reached 2 hours, any idea why i need to connect it again ? any help would be appreicated Keith

for example a MR76 that has 4 x 4 MIMO, if there are 5 x devices with 3 antennas connecting to it, 5 of the devices will has a speed of 300 Mbps ? will this speed will decrease if more devices connecting at the same time ? so the bottleneck will be the lan adapter of MR76 ? if the lan switch are using 1 giga ethernet ?

Yes it’s the throughout I want to talk about not the data rate, as we will have a meeting with our customer to propose to use MR36 ratter than MR44, due to budget issue. mr36 support 2.4ghz 2:2x2 and 5Ghz 2:2x2 whereas mr44 support 2.4Ghz 2:2x2 and 5Ghz 4:4x4 Need to explain to customer if they are using mr36 for 2.4ghz. The performance are still ok compared to mr44 on 2.4Ghz, just wonder if you can provide me the overhead of this ? Thanks

Dear All, I have a question would like to ask on MR44, for MR44 2.4Ghz is using 2:2x2 and 5Ghz is using 4:4x4, for instance there are 8 endpoints connecting to 5Ghz at the same time, will the data rates for endpoints will get slower compared to have 4 endpoints connecting to 5Ghz at the same time ? i have an example below, please correct me if my concept is wrong, Thanks case1: 600Mbps for 4: 4 x 4 - if there are 4 endpoints connecting to 5Ghz, the data rates for each endpoint will be 150Mbps case2: 600Mbps for 4: 4 x 4 - if there are 8 endpoints connecting to 5Ghz, the data rates for each endpoint will be 75Mbps
